Description
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a display panel.
Description of the Related Art
A conventional display panel that has narrowed frame by not
providing groups of wirings including transparent electrodes
provided between a panel end portion of a panel body and a driver
IC for driving a display unit, so as to reduce an interval defined
between the panel end portion and the driver IC, has been
known.
Input terminals of the driver IC are normally disposed along a
first short side of the driver IC. However, when the number of
input terminals is large, and the input terminals cannot be
disposed along the first short side, the input terminals may be
disposed along the first long side of the driver IC.
In such case, when the above method for aligning the input
terminals is adopted, the number of input terminals which can be
disposed along the first short side of the driver IC depends upon
an interval defined between the input terminals. Therefore, the
area of the driver IC becomes greater to an increase in number of
input terminals.
On the other hand, Japanese Patent Application Laid-open (JP-A) No.
10-214858 discloses the configuration in which plural input
terminals of a semiconductor chip are disposed along first long
side of the semiconductor chip, and along the second long side of
the semiconductor chip.
However, in the configuration disclosed in JP-A No. 10-214858,
wirings are drawn from both of the long sides of the semiconductor
chip outward of the driver IC. Therefore, the above configuration
cannot be applied to a display panel that has no wiring interposed
between a panel end portion and the driver IC.
SUMMARY OF THE INVENTION
The present invention provides a display panel that may suppress
increase in area of a driver IC due to increased numbers of input
terminals.
A first aspect of the invention is a display panel including: a
panel body including a display section; a rectangular driver IC,
provided between the display section and a panel end portion of the
panel body and disposed with the display section in a longitudinal
direction, which drives the display section; a first input terminal
group in which input terminals are disposed at intervals along a
first long side of the rectangular driver IC that faces the panel
end portion; a second input terminal group in which input terminals
are disposed at intervals along a second long side of the
rectangular driver IC that faces the display section; a first
wiring group that is connected to the first input terminal group,
that is formed on the panel body between the rectangular driver IC
and the panel body, that passes under a first short side of the
rectangular driver IC and that extends out from between the
rectangular driver IC and the panel body; and a second wiring group
that is connected to the second input terminal group, that is
formed on the panel body between the rectangular driver IC and the
panel body, that passes under the second long side of the
rectangular driver IC and that extends out from between the
rectangular driver IC and the panel body.
According to the first aspect of the present invention, the first
wiring group, that has reduced intervals between the wirings or the
smaller width of the wiring than the first input terminal group, is
disposed along the first short side in the driver IC. Due thereto,
in the first aspect of the present invention, the input terminals
of the first input terminal group, that are to be respectively
connected to the first wiring group, is disposed, according to the
number of the wires of the first wiring group that may be disposed
(wired) along the first long side in the driver IC.
Therefore, according to the first aspect of the present invention,
the number of input terminals that can be disposed may increase,
since the input terminals are disposed along the first long side in
the driver IC, when compared with, for example, a case where the
first input terminal group is disposed along the first short side
in the driver IC. Moreover, the first aspect of the present
invention may suppress the increase in area of the driver IC due to
increased number of input terminals.
In the display panel according to the first aspect, each of the
wirings is not drawn from the first long side in the driver IC to
the panel body. Accordingly, the present invention may be
particularly effective in a so-called "narrowed edge panel" in
which a frame is narrowed by aligning no wire between a panel end
portion and the driver IC.
Note that, the term "narrowed edge panel" refers to a panel
provided with configuration where no inputting wiring is formed
between the driver IC and the panel end portion.
A second aspect of the invention, in the above first aspect, the
first input terminal group and the second input terminal group may
be sequentially disposed from an end portion of the first short
side of the rectangular driver IC; and wirings of the first wiring
group that are connected to the input terminals of the first input
terminal group and that are disposed further toward a second short
side of the rectangular driver IC than the second input terminal
group, may extend out from under the second long side of the
rectangular driver IC.
According to the above aspect, even when the number of the
terminals in the first input terminal group is increased, and some
of the wirings in the first wiring group may not extend out from
the first short side of the driver IC, some of the wirings in the
first wiring group may extend out from the second long side in the
driver IC.
A third aspect of the invention, in the above aspects, a width of
wirings of the first wiring group that extend out from under the
first short side of the rectangular driver IC may be smaller than a
width of the input terminals of the first input terminal group and
the second input terminal group.
According to the above aspect, when compared with, for example, a
case where the first input terminal group is disposed along the
first short side of the driver IC, the number of input terminals
that can be disposed may be increased, since the width of the
wiring in the first wiring group is smaller than width of each
terminal. Accordingly, the above aspect of the present invention
may suppress the increase in area of the driver IC due to increased
number of input terminals.
A fourth aspect of the invention, in the above aspects, intervals
between wirings of the first wiring group and intervals between
wirings of the second wiring group may be smaller than the
intervals between the input terminals of the first input terminal
group and the intervals between the input terminals of the second
input terminal group.
According to the above aspect, when compared with, for example, a
case where the first input terminal group is disposed along the
first short side of the driver IC, the number of input terminals
that can be disposed may be increased, since the interval between
the wirings in the first wiring group is smaller than the interval
between the terminals in the first input terminal group.
Accordingly, the above aspect of the present invention may suppress
the increase in area of the driver IC due to increased number of
input terminals.
A fifth aspect of the present invention, in the above aspects, a
number of input terminals disposed along both of the long sides of
the rectangular driver IC may be larger than a number of input
terminals that can be disposed at either short side of the
rectangular driver IC.
According to the above aspect, when compared with, for example, a
case where the first input terminal group is disposed along the
first short side of the driver IC, the increase in area of the
driver IC due to increased number of input terminals may be
suppressed.
A sixth aspect of the present invention, in the above aspects, the
first wiring group may extend from the first input terminal group
toward the second input terminal group, then may extend toward the
first short side of the rectangular driver IC before reaching the
second input terminal group, and may extend under the first short
side of the rectangular driver IC; and the second wiring group may
extend from the second input terminal group toward the second long
side of the rectangular driver IC, and may extend under the second
long side of the rectangular driver IC.
According to the above aspect, the first wiring group may be wired
in the panel body between the first input terminal group and the
second input terminal group of the driver IC.
A seventh aspect of the present invention, in the above aspects,
the rectangular driver may IC include a CPU interface and a driving
circuit; and the first input terminal group and the second input
terminal group may be groups of input terminals for the CPU
interface and the power source circuit.
According to the above aspect, the first input terminal group and
the second input terminal group may work as groups of input
terminals for the CPU interface and the power source circuit.
An eighth aspect of the present invention, in the above aspects,
the wirings of the first wiring group and the second wiring group
may be transparent electrodes.
According to the above aspect, the first wiring group and the
second wiring group may be transparent electrodes.
According to the above aspects, the present invention provides a
display panel that may suppress increase in area of a driver IC due
to increased numbers of input terminals.

DETAILED DESCRIPTION OF THE INVENTION
Hereinbelow, a description will be given of a display panel
according to an exemplary embodiment of the present invention with
reference to the attached drawings. Note that constituent elements
having substantially the same functions will be designated by the
same reference numerals throughout the drawings, and their
explanations may be omitted.
FIG. 1 is a view showing the schematic configuration of a display
panel according to an exemplary embodiment of the invention.
A display panel 10 of the exemplary embodiment according to the
present invention includes a panel body 12 formed into a
rectangular shape when viewed from the front. At substantially the
center of the panel body 12, a rectangular display section 14 is
disposed so that a longitudinal direction of the rectangular
display section 14 matches with a longitudinal direction of the
panel body 12.
One end of each transparent electrode 16, wired to the panel body
12, is connected to the display section 14. To the other end of
each transparent electrode 16, a driver IC 18 is connected.
The driver IC 18 is disposed between the display section 14 and a
panel end portion 12A of the panel body 12 (i.e., the outer
peripheral portion of the panel body 12) so that the driver IC 18
extends along the display section 14 in the longitudinal direction.
Namely, the driver IC 18 is disposed so that the longitudinal
direction of the driver IC 18 matches with the longitudinal
direction of the display section 14. The driver IC 18 outputs a
drive signal or the like, to the display section 14 through the
plural transparent electrodes 16. Signal is input to the driver IC
18 via plural transparent electrodes 20, that are connected to one
end of the driver IC 18, and are connected to the panel body
12.
The other end of each of the plural transparent electrodes 20 is
collected within a flexible board 22, to be drawn outward of the
panel body 12, and is connected to a CPU (not shown), a voltage
source device, or the like.
Note that, in order to achieve a narrowed edge, a space defined
between the panel end portion 12A and the driver IC 18 is made
minimum by not wiring any transparent electrodes 20 therebetween.
On the other hand, spaces for wiring the transparent electrodes 20
are defined in the panel body 12 between the driver IC 18 and the
display section 14 or in the panel body 12 in the longitudinal
direction of the driver IC 18. Note that the term "narrowed edge
panel" refers to a panel that has a configuration in which
inputting transparent electrodes 20 (wirings) are not disposed
between the driver IC 18 and the panel end portion 12A, in order to
reduce the area of the panel body 12. In general, a signal is input
into the driver IC 18 from the outside of the display panel 10 via
the transparent electrodes 20. In this case, the flexible board 22,
for example, is overlapped on the side of the panel 12, and the
driver IC 18 is electrically connected to the transparent
electrodes 20. Accordingly, when the transparent electrodes 20 are
drawn between the driver IC 18 and the panel end portion 12A, it is
necessary to secure the space for the overlap between the driver IC
18 and the panel end portion 12A, which may result in increase of
area of the panel body. Therefore, in the conventional display
panel, the increase in area of the panel body 12 has been
suppressed by interposing no transparent electrode 20 between the
driver IC 18 and the panel end portion 12A.
Note that, since the length of the display section 14 in the
longitudinal direction is generally longer than the longitudinal
direction of the driver IC 18, the transparent electrodes 20 are
drawn in a horizontal space of the driver IC 18.
Next, the driver IC 18 of an exemplary embodiment of the present
invention is described in detail.
FIG. 2 is a functional block diagram illustrating the schematic
configuration of the driver IC 18.
The driver IC 18 includes a CPU interface 100, a control circuit
102, a power source circuit 104, and a driving circuit 106.
The CPU interface 100 receives an input signal from the CPU (not
shown), via the transparent electrodes 20 (i.e., signal wirings),
and transmits data based on the input signal to the control circuit
102.
The control circuit 102 produces display data based on the data
received from the CPU interface 100, and transmits the display data
to the driving circuit 106.
On the other hand, the power source circuit 104 receives a voltage
from the voltage source device (not shown), via the plural
transparent electrodes 20 (i.e., power source wirings), generates a
voltage required for the driving circuit 106, and supplies the
required voltage to the driving circuit 106.
The driving circuit 106 outputs the voltage generated in the power
source circuit 104 and an output signal, in accordance with the
display data, to the display section 14 in a desired drive
waveform, via the plural transparent electrodes 16.
FIG. 3 is a view showing the arrangement of input terminals and
output terminals in the driver IC 18. Note that the wirings
connected to each of the terminals are omitted in FIG. 3.
Output terminals 200 are the output terminals for the driving
circuit 106 in the driver IC 18, that outputs the signal in the
above desired drive waveform. In order to provide a narrowed edge,
the plural output terminals 200 are disposed along a long side 18A
facing the display section 14 in the driver IC 18. The other ends
of the above plural transparent electrodes 16 are connected to the
output terminals 200, respectively.
In contrast, input terminals 202 are the input terminals for the
CPU interface 100 and the power source circuit 104 in the driver IC
18, that receives the signals from the CPU (not shown) or the
voltage from the voltage source device (not shown). The plural
input terminals 202 are disposed at intervals along the first long
side 18B of the driver IC 18 that faces the panel end portion 12A,
and are disposed at intervals along the second long side 18A of the
driver IC 18 that faces the display section 14.
Hereinafter, the plural input terminals 202 disposed with intervals
along the first long side 18B of the driver IC 18 that faces the
panel end portion 12A are referred to as a first input terminal
group 204. Further, the plural input terminals 202 disposed at
intervals along the second long side 18A of the driver IC 18 that
faces the display section 14 are referred to as a second input
terminal group 206.
In order to suppress an increase in area of the driver IC 18, it is
preferred to sequentially dispose the first input terminal group
204 and the second input terminal group 206 from the first short
side 18C (a left short side in FIG. 3) of the driver IC 18, and is
preferred not form a group of input terminals or the like on the
second short side 18D (a right short side in FIG. 3) of the driver
IC 18. However, a dummy terminal may be disposed on the second
short side 18D of the driver IC 18 to enhance adhesion strength.
Further, counterparts of the input terminal group formed on the
first short side 18C of the driver IC 18 may be formed on the
second short side 18D of the driver IC 18.
FIG. 4 is a partially enlarged view of the driver IC 18 enclosed by
a dot line X of FIG. 3.
The plural transparent electrodes 20 are connected to the first
input terminal group 204. Note that, hereinafter, the transparent
electrodes 20 connected to the first input terminal group 204 are
referred to as a first wiring group 300.
The first wiring group 300 is formed on the panel body 12 between
the driver IC 18 and the panel body 12. Further, the first wiring
group 300 extends from the first input terminal group 204 toward
the second input terminal group 206, then extends toward the first
short side 18C of the driver IC 18 on the way toward the second
input terminal group 206, and then extends out from between the
driver IC 18 and the panel body 12 through under the first short
side 18C of the driver IC 18. In this case, a wiring that extends
from the input terminal 202 formed right side of a certain input
terminal 202 (i.e., on the second short side 18D side) circumvents
a wiring drawn from the input terminal 202 formed left side (i.e.,
on the first short side 18C side of the driver IC 18), and extends
leftward above the wiring drawn from the input terminal 202 formed
on the left (i.e., on the second long side 18A side of the driver
IC 18).
Note that some of the wirings (i.e., a wiring arranged lowermost in
FIG. 4) in the first wiring group 300 extends immediately toward
the first short side 18 of the driver IC 18 without extending from
the first input terminal group 204 toward the second input terminal
group 206, and extends out from under the short side 18C.
Further, the width of the wiring in the first wiring group 300 that
extends under the first short side 18C of the driver IC 18 is
formed smaller than width of the terminals in the first input
terminal group 204 and the second input terminal group 206.
Furthermore, the intervals between the wirings that extend from
under the first short side 18C of the driver IC 18 in the first
wiring group 300 is formed smaller than the intervals between the
terminals of the first input terminal group 204.
On the other hand, rests of the above plural transparent electrodes
20 are connected to the second input terminal group 206. Note that,
hereinafter, the transparent electrodes 20 connected to the second
input terminal group 206 are referred to as a second wiring group
302.
The second wiring group 302 is formed on the panel body 12 between
the driver IC 18 and the panel body 12. Further, the second wiring
group 302 extends from the second input terminal group 206 toward
the second long side 18A of the driver IC 18, and then extends from
between the driver IC 18 and the panel body 12 through under the
second long side 18A of the driver IC 18. Note that, some of wiring
in the second wiring group 302 (i.e., a wiring arranged lowermost
in the second wiring group 302 in FIG. 4) does not extend from the
second long side 18A to the panel body 12, but extends from under
the first short side 18C of the driver IC 18, as the first wiring
group 300.
The interval between the wirings of the second wiring group 302 is
made smaller than the intervals between the terminals of the second
input terminal group 206.
When connecting the first wiring group 300 to the first input
terminal group 204, while designing the display panel 10, the input
terminal 202 nearest to the first short side 18C of the first input
terminal group 204 is first connected. At this time, the number of
wirings to be connected to the input terminals 202 is the number of
wirings that can pass between the first input terminal group 204
and the second input terminal group 206, or less. Note that, in
FIG. 4, maximum number of wirings that can pass between the first
input terminal group 204 and the second input terminal group 206
are wired. Further, when connecting the second wiring group 302 to
the second input terminal group 206, it is wired from between the
first input terminal group 204 and the second input terminal group
206 if there still remains a space capable of allowing the wiring
to pass therebetween. However, if there remains no space, it is
wired from the second input terminal group 206 toward the second
long side 18A of the driver IC 18.
Next, explanation will be made on a configuration of a comparative
example. The comparative example used herein illustrates the
configuration of a conventional driver IC. FIG. 6 is a partially
enlarged view of a driver IC in the comparative example. In a
driver IC 500 of the comparative example (hereinafter referred to
as a comparative driver IC 500), input terminals 502 are disposed
at intervals along the first short side 500C of the comparative
driver IC 500. In the case where the number of input terminals 502
is large such that the input terminals 502 cannot be disposed along
the first short side 500C, the input terminals 502 are disposed at
intervals along a long side 500A on the side of a display section
14 in the comparative driver IC 500. In this case, the number of
the input terminals 502 that can be disposed along the first short
side 500C of the comparative driver IC 500 depends upon, not the
intervals between wirings 504 connected to each of the input
terminals 502, but the intervals between the input terminals 502 or
the width of the input terminal 502. Further, when the number of
the input terminals 502 that cannot be disposed along the first
short side 500C increases, length of the long side 500A, in which
the input terminals 502 are disposed, increases. Accordingly, the
area of the comparative driver IC 500 increases.
On the other hand, according to the exemplary embodiment of the
invention, the first wiring group 300, having intervals or width
that are smaller than the intervals or the width of the input
terminals of the first input terminal group 204, is disposed along
the short side 18C of the driver IC 18. Due thereto, according to
the number of wires of the first wiring group 300 that can be
disposed along the first short side 18C of the driver IC 18, input
terminals of the first input terminal group 204 can be disposed
along the first long side 18B of the driver IC 18.
Accordingly, in comparison with the comparative driver IC 500, in
which the input terminals 502 are disposed along the first short
side 500C of the comparative driver IC 500, the input terminals 202
are disposed along the first long side 18B of the driver IC 18, so
that the number of input terminals 202 that can be disposed
increases. Therefore, the present invention may suppress the
increase in area of the driver IC 18 due to increased number of
input terminals 202.
Namely, in the exemplary embodiment of the present invention, since
the first input terminal group 204 and the second input terminal
group 206 are disposed along the long sides 18A and 18B of the
driver IC 18 respectively, the area of the driver IC 18 also
increases due to the increased number of input terminals 202.
However, in the comparative example, when the number the input
terminals 502 (i.e., the input terminals 502 disposed along the
long side 500A of the driver IC 500) exceeds the number of input
terminals 502 that can be disposed along the short side 500C
(namely, when the entire number exceeds 14 in FIG. 6), the present
invention may suppress the increase in area of the driver IC 18 due
to increased number of input terminals 202, by the reduced amount
of the intervals between the wirings or the width of the wiring of
the first wiring group 300.
Further, according to the exemplary embodiment, even when the
driver IC 18 shown in FIG. 4 is turned at 180.degree., the wirings
can be fixedly wired in the panel body 12, as shown in FIG. 5.
Therefore, both of right and left alignments can be coped with
(FIG. 4 and FIG. 5) even when no wiring can be wired between the
driver IC 18 and the panel end portion 12A.
The present invention is not limited to the above exemplary
embodiment, and various modifications, alterations, and
improvements can be implemented.
For example, a case where the wirings connected to the first input
terminal group 204 and the second input terminal group 206 are the
transparent electrodes has been described, the wirings may not be
transparent. In addition, materials of the electrodes are not
particularly limited, as long as they are conductive.
Moreover, in FIG. 4, a case where the first wiring group 300
extends from the first input terminal group 204 toward the second
input terminal group 206, extends toward the first short side 18C
of the driver IC 18 on the way toward the second input terminal
group 206, and extends out from the short side 18C to the panel
body 12, has been described. However, as long as the first wiring
group 300 is extended from the short side 18C to the panel body 12,
its arrangement or shape under below the driver IC 18 may take any
aspects. For example, the first wiring group 300 may extend from
the first input terminal group 204 toward the short side 18C with a
curve.
Further, as shown in FIG. 5, in a case where the number of input
terminals 202 formed downside becomes larger than the number of
input terminals 202 formed upside, a configuration in which the
wirings extending from input terminals 202 by the number of
excessive input terminals leftward are extended from upside can be
applied to the case where wiring are extended from leftward, as
shown in FIG. 4.
Note that, although the input terminals 202 are disposed with the
equal intervals in FIG. 4, it is preferable to form input terminals
with separate intervals rather than equal intervals in
consideration of a crosstalk with an adjacent terminal.
